The increased use of alternative deicers to rock salt and introduction of anti-icing prior to winter events using concentrated brines has, in some cases, been associated with deterioration of concrete, especially at joints in pavements. While many commercial products are being used, most either are sodium, calcium, or magnesium chlorides, or mixtures of chlorides. In this study, the effects of different concentrations of calcium and magnesium chlorides on concrete are compared to that of sodium chloride. This study, completed in 2009, found that highly concentrated calcium and magnesium chloride brines caused damage to concrete exposed to low-temperature and freezing temperature cycles by formation of expansive oxychlorides. These results were confirmed by subsequent extensive research performed by others. This paper focusses on concrete performance when exposed to the different forms of chlorides.

It is well known that the steel–concrete interface (SCI) influences corrosion of steel in concrete. Numerous factors related to the SCI have been hypothesized to affect the mechanism of corrosion initiation and propagation, including steel surface characteristics, interfacial concrete properties (voids, cracks, etc.), and conditions related to the exposure (e.g., SCI moisture state). This contribution offers an overview of current knowledge on these aspects. Additionally, recent advances toward a fundamental understanding of corrosion-related processes occurring at the SCI are highlighted, including a novel experimental methodology for studying the steel surface behavior, imaging of the SCI moisture state, and the impact of macroscopic voids. Finally, perspectives for future research are given.

Corrosion of steel in concrete involves interactions between net anodic and cathodic regions that may extend into the cm, m or multi-m range. Such broad macrocells conveniently help corrosion detection methods based on half-cell potential surveys. However, the macrocells can also complicate the interpretation of polarization measurements of corrosion rates, leading to over or under estimates depending on the chosen placement of the sensor electrodes. Corrosion macrocells can also make interdependent the corrosion initiation and propagation stages of contiguous parts of a structure, by mutually affecting chloride threshold values and corrosion rates. Damage evolution forecasts change considerably when interdependence is taken into consideration, an issue of importance in creating next generation models. This paper addresses understanding by the corrosion in concrete community in a selection of these issues, and anticipates challenges to be resolved next.

Internally cured concrete was used to repair bridge decks of the Wilson Dam in Muscle Shoals, AL, USA, and to provide a 100-year service life. The article discusses characteristics of internally cured concrete and the benefits of using it, as well as lightweight aggregates needed to produce such concrete and their properties.
